This report presents the findings of an assessment of the IdentiFlight® (IDF) avian detection system installed at Cattle Hill Wind Farm (CHWF) in Tasmania’s Central Highlands region. The IDF system was designed in the United States specifically to reduce Golden Eagle mortalities on wind farms and has been installed at CHWF as part of a technology trial to assess the effectiveness of the system at preventing collisions of threatened Tasmanian eagles on wind farms. The species of concern are the Tasmanian Wedge Tailed Eagle (Aquila audax fleayi) (WTE) and the White Bellied Sea Eagle (Haliaeetus leucogaster) (WBSE). CHWF is the first Australian project to implement this innovative technology. This report has been prepared by Goldwind Australia Pty Ltd on behalf of Wild Cattle Hill Pty Ltd (WCHPL) in satisfaction of EPBC Approval 2009/4839 Condition 6C, which requires an 18-month trial of the technology, incorporating an end of trial report assessing effectiveness against requirements outlined in the Collision Avoidance Detection Plan (CADP) approved under condition 6A.
